Question
What is filtration?
✓
Answer
When one component of a mixture is soluble in water and other component is insoluble in water, the soluble component gets dissolved and insoluble one is separated by filtering the solution.
The process by which insoluble substance can be separated from a solution, by passing that solution through a porous paper (filter paper) is called filtration. During filtration, the solid insoluble substance is retained at the filter paper as residue while the liquid free from any suspended matter passes through the filter paper and is collected as filtrate. This filtrate may be warmed to dry to obtain soluble component. Figures (a), (b), (c) show the folding and use of filter paper in filtration.
